I'm having the same issue across different browsers and PCs. The site seems to work briefly before eventually returning only a white page. The browser reports a bunch of errors similar to:
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://graph.oculus.com/graphql?locale=en_US. (Reason: CORS preflight response did not succeed).
I'm having other issues too that might be related. The Oculus Platform Util always returns a server/network error when attempting to upload a build and my support tickets seem to not be going through (no automated reply or response in ~1-2 weeks).
